When creating a new account in iRedMail I noticed that the maildir is created in the format storagebasedirectory/vmail1/domain/firstletter/second/third/account-timestamp. In order to simplify the migration process from my older server I need that the format to be something like storagebasedirectory/vmail1/domain/account (without timestamp and the letters directories). How can I change this? I suppose it's some sort of scrip that is run every time we add a user in the iredmail panel.

Another question, is there a trial version of the iRed Panel Pro fo MySql?
